The cam 39 is vin fixed relation `to abutment 28, Aandthe rockers are provided with rollers Gil, onthe shorter arms 57,'Which engage Vwith cam 39, and actuate the rockers and thereby movethe pistons 59 in passing said abutment 28. On passing saidabutment, the rollers 65,011 the longer arms ofthe rockers, will engage with cam 10, and, thereby return the pistons to operative position; the pistons being then maintained in position by centrifugal force and the actionpof springs`63. Grease cups 66 are provided for lubrication of the pistons 59 and packings 60.`

Referring to Figs. 6,11, 12,13, an oscillating valve 67 is mounted in chamber 38; lthe valve having a compartment 68 open to the atmosphere, and an inner com-1` partment 69. AIn the an' compressing position, port registers with port 42. allow- `ing the air to enterthe piston chamber 27 The pistons VWithin the chaniber then oom- A press the air, and, `port 12 being closed by the valve, the compressed air passes through portll@ into chamber 15. and thence tlnougli the spring-actuated valve 71, and port 46, into the inner ,compartment 69, vwhich is provided with a port 72, registering with port 37 through Which the compressed fluid passes to duct 36 and the segmental .grooif'ed chamber 35." i

To utilize the compressed fluid for rotating member 18, the `Valve 67 is `reversed shown in Figs. 1 and 6,` with port 72 registering With port 37; the compressed" fluid passing through said ports, and thence through' port 73 registering with port 41, and actingupon pistons 59, finally exhaust# ing through ports 43 and 70, into compartment 68.

The independent internal gearv member Y intermeshes With pinions 76, mounted on studs 77.projecting from member 23. Mem!v ber 75 is provided :With ratchets 78 and 79, adapted Vto engage with corresponding ratch ets in hub, 31,.of member 26.` and iatchets in member 48. When member is actuated b the motor Oear member 7 5 will be forced y 9 C fromengagementA with meniber 26, and into engagement with member 48. In this poand sition, pii'iions 47 6, interineshing with gear inembei 75 and fixed pinion 74:' on member rand fan 55. Member 7 5. bein lio'hter'than member 26, will be automatically shifted by the turning movement of member 23.

l In starting the motor, member 26 is kept fionifrotatiiig, as hereinafter shown, and

-member 48 is actuated by the fiuid pressure.

The turning 'moven'ient of member L18 forces the gear member 75 into engagement With the relatively stationary member 26, which prevents rotation of member 75. The pin-V ions 7 6, being driven by pinion 7e fixed to member 48, Will run around the internal gear member 75, Vcausing member 23 to rotate, and thereby effecting rotation of thc motor. The gear ratios of pinions 74, 76, and internal gear member 75, is such, that effective speed of rotation is transmitted to member 23. Y 1

A.Y pressure retaining member 80, in abut* nient 28, is yieldingly forced into engagement With member .48, by a spring 81, preventing leakage from one portion to another of chamber27.

V A yoke 82 is secured by a nut'83, to sup- Y porting member 21. A; conical member 84, provided With. an annular chamber 85, is

Yrotatively mountedl on sleeve member '86. `which is provided with a spiral flange 8'( in engagement with membery 84. Upon rotating member 84 in one direction, the cham-` ber 85 will register with the` segmental chamber 35, of member 26. which is fixed to member 8l is thus'placed in communication with duct 36, and .is

adapted to transmit the compressed fluid.

to and from chamber 27 The tube 88. Y

Assuming that a tank or other source of compressed fluid (not shown), is in comvinunicati'on Withthe tubular member 89. the

pressure will pass through portv 90, in valve 91, and thence through a tube 92, to a'valvc chamber 93, first forcing the piston 94E and piston rod 95 outward. thereby operating 4the crosshead 96, and through link 97.

vtardly moving crosshead has, through link 99, and'lever 100, actuated the brake band 101 to operative position. This prevents rotation of the `outer compressor' member 26. The inner rotary member, being free to re volte independently, ivill be actuated b v they pressure, vand as previously shown, this independent rotation isemployed to actuate ble and annulaiinembers are light in Weight,

andl are adapted tobe mounted in the space and position usually occupied by the fan of an internal lcombustion engine. The change o from anair motor `to acompressor is automatically accomplished by a spring 139, acting against the rocker. 109, and-its support 142,: which is fixed to member Q6. During the revolution of member 26, the pawl 106, and flink 107,'ivould tend to fly outward, but are retained in operative position relative tothe ratchet Wheel 105, byV a "fixed member 143, projecting frommember 26, and limiting the outward movement.
